Advances in Vertical and/or short take-off and landing (V/STOL) aircraft technology

Sometimes long runways  required by conventional aircrafts aren’t available to use or there is a need for an aircraft to use no runways at all.  Vertical take-off and landing VTOL technology means aircraft can theoretically take off and land almost anywhere, making them far more flexible. They’re also able to perform various manoeuvres not possible with a conventional plane; a significant advantage for aircraft in combat situations. What’s more, VTOL aircraft, such as drones, that use electric motors are more energy efficient than those using jet engines.
